Ultra-flat Quartz Coated Glass

Order Code: S151


(excluding Taxes)


These ultra-flat glass substrates are coated with a 20 nm layer of synthetic quartz.

For many applications standard glass is simply not good enough due to either surface roughness or wettability. These synthetic quartz covered substrates are useful for a variety of activities such as absorption/PL measurements, OFET fabrication and surface profilometry where superior wettability and/or flatness are required.

Update: The substrates now come with small squares of ITO in the corners to help identify the SiO2 coated side.


Substrate size 20 mm x 15 mm
Thickness 1.1 mm
Glass type Polished soda lime, float glass
Substrate coating 20 nm SiO2
Refractive index 1.5
Flatness 50 nm per 20 mm (typical)
Glass roughness 1 nm RMS (by AFM)
